Yes and no. Connectivity tests have been an important part of the early work so far but depending on the airline and route, we've consistently averaged 6Mbps upload pre-Covid which has been sufficient. Passenger volume is significantly down post-Covid and that upload number has been about 3x lately. Wifi coverage is ~100% over land and the North Atlantic, so reliability of service is a negligible issue. American Airlines has recently upgraded their in-flight wifi to Gogo's 2Ku systems and we've hit 15Mbps up on those flights, but as another commenter mentioned, the plan is to carve out dedicated bandwidth onboard the flight for better connectivity. A connection is only optional, as we save the recorded data and can upload once the flight lands using wifi on the ground (much cheaper, but with a few hours of latency between recording and becoming a map tile).
